Sample size (or number of clusters) by treatment arms
The jobseeker profiles and applications will be balanced by gender, i.e., approximately 150 jobseekers and 10,000 applications in each gender group. We plan to randomly assign five levels of salaries, so each salary level will have approximately 4,000 applications. Together, we have 10 gender-by-salary arms, each arm with approximately 2,000 application observations.
